Hi,
at first read the topic "How to report a bug".
I am curious why Base isn't labeled Core, so maybe try at first to set the game back to engl. just to check if that helps.
1.2.3.3 is the latest CE version. And at last at github there is the right packageID for Harmony which is the only required mod for CE.
Since the that version is from Nov.1 many other would report an issue and a hotfix would made pretty fast, so i think the problem is at your end.
Try to delete Harmony and CE folder from Mods and reinstall them(or unsubscribe and resubscribe) to be sure you don't have any unwanted old file's left at these mods.
